To all lwhom t may concern:

Be it known that I, GEORGE H. Bumm, a citizen of the United States, anda resident of Nanuet, Rockland county, and State of New York, haveinvented certain new and useful Improvements in Dump-Buckets, of whichthe following is a specification, reference being had therein to theaccompanying drawings, in which- Figure 1 is a front elevation of a dumpbucket provided with my improved bottom locking and releasing means;Fig. 2 a side elevation; Fig. 3 a horizontal sectional view on the lineIII-III of Fig. 1, showing the bottom locking and releasing means inplan view; Fig. 4; a detail vertical sectional view of one of the latchsockets carried by the bottom; and Fig. 5 a detail transverse verticalsectional view showing the bottom locking means in latched position.

One of the objects of this invention is to provide a bottom locking andreleasing means of very simple and strong construction wherein thelocking dogs will be automatically engaged with the latch sockets whenthe bottom is brought into closed position, the locking dogs beingpivotally mounted on the front of the bucket and the latch sockets beingsecured to the front edge of the bottom.

Another object of the invention is to provide an operating cam of suchconstruction pivotally mounted on the front of the bucket and operatingthe locking dogs in such manner that said dogs will be held in positionto enter the latch sockets when the bottom is swung to its closedposition.

Another object of the invention is to provide latch sockets on thebucket bottom of such construction that they will receive the lockingdogs and automatically force them into locking engagement with the latchlianges.

Referring to the various parts by numerals, 1 designates the body of thebucket which may be of any suitable shape and size, and 2 the bottomthereof. The bottom is carried by the hinged arms 3 which are journaledat 4: on the back or rear side of the bucket. On the front of thebucket, approximately in the center thereof, is pivotally mounted anoperating cam 5. This cam is provided on opposite sides of its pivotalcenter with curved eccentric cam slots 6, one of which extends upwardlyand outwardly, and the other downwardly and outwardly from points in ahorizontal plane with the center of the cam pivot. At the outer' end ofeach of these cam slots is formed a radial outwardly extending slotextension 7. This cam is also formed with a radial operating arm orhandle 8.

Pivoted on the front of the bucket near the lower edge thereof are twolocking levers 9, one on each side of a vertical plane passing throughthe center of the cam pivot. Each locking lever extends upwardly and isprovided at its upper end with a yoke 10 between the arms of which theoperating cam fits. The upper ends of the arms of each yoke is connectedtogether by a horizontal pivot 11 which passes through the adjoining camslot of the operating cam, said pivots being in a horizontal planepassing through the center of the cam pivot, as shown clearly in Fig. 1.The lower end of the locking lever extends below the bottom of thebucket and each is provided with a locking dog 12 which inclinesoutwardly and downwardly, as shown clearly in Fig. 1, its upper, outercorner being cut away to form the outwardly and downwardly inclined camsurfaces 13, for a purpose which will be fully hereinafter described.

On the bottom of the bucket at the front edge thereof are secured twolatch sockets 14. These latch sockets extend forward of the front edgeof the bucket and are provided with the apertures 15 through their uppersurfaces. Each latch socket is provided at its inner side with thedownwardly and outwardly inclined cam surface 16 and at its outer sidewith the inwardly extending locking flange 17. By reference to Fig. 1 itwill be readily seen that the locking dogs 12 in their latched positionsengage under the flanges 17 and hold the bottom in its closed position.

The operation of the device is as follows Assuming the parts to be inthe position shown in Fig. 1, an upward movement of the handle S of theoperating cam will force the upper ends of the locking levers outwardly,thereby swinging inwardly or toward each other the locking dogs andreleasing them from the flanges 17 of the latch sockets. As the bottomswings downwardly the locking flanges will contact with inclined or camsurfaces 13 of the locking dogs and force them inwardly, therebythrowing the upper farther inwardl ends of the locking levers outwardlyinto the slot-extension 7 of the operating cam. 1n this position theoperating cam will be locked in its horizontal position and the lockingdogs will be held in their inward position and the bottom will be freeto swing downwardly to discharge the contents of the bucket. Then it isdesired to close the bucket, in the ordinary practice the bucket islowered to permit the bottom to rest on the ground or other suitablesupport and the bucket lowered to meet the bottom. 1n this action thelower corners of the locking dogs 12 will `enter the apertures 15 of thelatch sockets and will contact with the cam surfaces 16 and ridedownwardly thereon. These cam surfaces will swing the locking dogsoutwardly sufficiently to free the pivots 11 from the slot extensions 7and thereby permit the operating cam to drop to its normal position. Theupper ends of the locking levers will be thrown still by the lcam 'slotsand the locking dogs wil be forced outwardly under the flanges 17 of thelatch sockets, thereby locking the bottom in its closed position. Thebottom cannot be released until the handle 8 is again lifted to swingoutwardly the upper end of the locking levers.

From the foregoing it will be seen that I provide an exceedingly simple,strong, durable and eflicient locking and releasing means for 'thebottom of dump buckets. It is also manifest that the `automatic lockingof the bot-tom to the bucket in its closed position is absolutelycertain under all conditions by merely lowering the bucket to bring thebottom in place. The parts of the apparatus are simple and may be madeof suflicient strength to stand the hard usage to which apparatus ofthis character .are subjected.

Having thus `described my invention, what I claim as new and desire tosecure by Letters Patent, is z- 1. A dump bucket comprising the body ofthe bucket, a bottom hinged thereto, a locking lever pivoted on thebucket and provided with a locking dog at its lower end, a latch socketconnected to the bottom Aand 1arranged to receive the locking dog, anoperating cam mounted on the bucket and formed with an eccentric camslot with a radial slot extension at one end of the cam slot, pincarried by the operating lever and engaging said slot, and means wherebywhen the locking dog is released from the latch socket the upper end ofthe locking lever will .be thrown into the radial slot extension of thecam slot to retain the locking dog in its released position.

2. A dump bucket comprising the bucket proper, a swing-ing bottomtherefor, a locking lever provided with a locking dog kat its lower end,a latch socket connected `to the bottom, means whereby when the lbottomis brought to its closed position the flocking dog will be thrown intoits latehed position, means whereby when the bottom is released the.locking dog will be thrown into its released position and latched insuch position until the bottom is again brought toits closed position,and means on the bottom to engage the locking dog to throw it to itslocked position when the bottom is closed.

3. A `dump bucket comprising a bucket proper, a bottom therefor, apivoted operating cam mounted on the front 4of the bucket, said cambeing formed with ldiametrically arranged curved eccentric slots, eachslot having a radial outwardly extending eXtension at the outer end ofthe curved part, a pair of locking levers pivoted near the lower edge ofthe front of the bucket, the upper ends of said levers engaging lthe camslots, a locking dog formed von the lower end of each lever below itspivot, and a latch socket for each `dog connected to the bottom of thebucket lat the front edge thereof.

il. A dump bucket comprising a bucket propel', a bottom therefor, apivoted operating cam mounted on the front of the bucket, said cam beingformed with diametrically arranged Vcurved eccentric slots, each slothaving a radial outwardly 'extending eXtension at the outer end yof thecurved part, a pair of locking levers pivoted near the lower edge of thefront of the bucket, the upper' ends of said levers `engaging the -eamslots, a locking dog formed on the lower end of each lever below itspivot, a latch socket for each ldog connected to the bottom of thebucket at the front ledge thereof, Aeach of said sockets being formedwith a cam surface to lengage the locking dog land throw it to itslocked position and its locking dog being formed with a cam surface to'throw `the locking dog to its full release position.

5. A dump bucket comprising the bucket proper, a bottom therefor, alocking lever pivoted on the bucket, .an operating cam mounted 'on thebucket and adapted to en gage 'the upper end of the Alocking lever tothrow it to its released position, a locking dog formed on the lower endof the locking lever, a latch socket Vsecured to the Ib'ottom of thebucket and adapted to receive fthe locking dog, means within the latchsocket to direct the locking dog 'to its latched position, means carriedby the locking dog to throw said `dog to i-ts eXtreme released position,and means to hold said `dog in said released position and in position tobe engaged by the latch socket.
